Google Cloud Professional Cloud Architect — Question 176

You are designing an application for use only during business hours. For the minimum viable product release, you'd like to use a managed product that automatically `scales to zero` so you don't incur costs when there is no activity.
Which primary compute resource should you choose?

Answer options

Correct answer: A

Explanation

Cloud Functions is the correct choice because it is designed to automatically scale down to zero when not in use, ensuring no costs are incurred during inactivity. In contrast, Compute Engine and Google Kubernetes Engine require you to manage instances that typically incur costs regardless of activity, and AppEngine flexible environment does not have the same automatic scaling feature as Cloud Functions.
